Abstract
An electrostatic imaging system using permanently imaged photopolymers as printing masters is being developed for producing multiple copies of four color proofs with high productivity and consistency. The imaging element - the master film, is based on electrical conductivity change induced by photopolymerization. After corona charging, the electrostatic latent images are developed by liquid toners and the toner images transferred to a receptor in sequence to yield a color proof. The original photopolymer images may be re-used to produce multiple copies by repeating the charging, toning and transfer steps.
